We've sold UV and red light tubes and channels since 1985. Our fluorescent tubes are industry standard F71T12 sized, the same as most tanning lamps. Our LEDs are near industry sized F71T8 but will work in any F71 device, regardless of what power supply/ballast it uses. If in doubt, just call us during business hours at 1-800-274-1744. We are happy to assist you.
